SPECIFICATION forming part of Letters Patent No.- 2'88,252, dated Novemberv 13, 188.3.

Application filed October 4, 1883. (No modeLl y To LEZ whom t may concern:

Be it known that We, ZOPHR YV. MORE and Mvnon H. TARBOX, of Lo ckport, in the county of Niagara and State of New York, have in- 5 vented certain Improvements in Snatchro struction and arrangement of the parts,whereby We are enabled to produce adevice which is strong and safe, and which is very easy of manipulation, all as hereinafter more fully set forth.

Figure 1 is a perspective v1e\v, and Fig. 2

is a transverse vertical section, of a snatchblock constructed on our plan.

- Snatch-blocks have long been in use, and` various methods of construction have been de- 2o" vised for opening and closing the space through which the rope is inserted or removed. The object of our invention is to produce a snatchblock that shall be strong, secure against accidents, and that can be easily manipulated.

As a general rule these blocks have been so constructed that when it was desired to release the side hook in case such a device was used, it was necessary to lift the block bodily or turn it up sidewise to release the hook, which is often very difficult, because of the great weight of the rope and fixtures which hang suspended from the block. Moreover, they have been so constructed that both hands were. required to release the hook or latch,

3,5 whichis also frequently inconvenient, especially in cases where the person is standing high up on a ladder or frame.

To construct dur improved snatch-block we provide the two cheek-pieces A and B as To the longer cheek, A, .We secure a metal strap, C, which has its upper end bent over at a right angle, so as to form a cross-bar,

I, at the'top, this cross-bar being enlarged Y and perforated at its center, so as to permit as shown. The end of this cross-bar I is made into a journal, o, on which We pivot a hook, H, the lower 'arm of which iscurved, so as to form the are of a circle concentric 5o with the journal o, or essentially so. To the the suspension-hook L to be journaled therein ,v

cheek-piece B We secure a double strap, D, composed of a single piece of metal bent in the form of a loop, and apply it to both sides of the cheek-piece, as shown clearly in Fig. 2. The inner portion of this strap D is preferably extended to the bottoni of the cheekpiece, and, if desired, both parts may be, it`

being secured by a rivet, c, near the bottom, y

and by the journal d of the pulley or sheave, and which, as shown in Fig. 2, passes through the straps of both cheeks. made enough longer than its cheek to form an open eye at its upper or bent portion for the hook H to engage in, as shown in Figs. 1

'Y and 2, so that when the hook is thus engaged the Weight Will be supported equally upon the two sides. In order to prevent this hook H from becoming accidentally disengaged, it is provided With a hole near its end, through which a split or spring pin, a., is inserted, this pin being secured to the rear portion. of the hook by a small chain or cord, `to prevent it from being misplaced or dropped. This chain b also serves another important purpose-viz., to draw the hook out of the eye Whenit is desired to uncouple them for the removal of the rope. In such case the oper# ator, having Withdrawn the pin, keeps hold of the chain, and by pulling back'on it detaches the hook from the loop, all of which can be done by one hand and with the utmost ease and facility, the hook being turned up, as shown in dotted lines in Fig. 1where it may remain out of the Way, and thus leave an unobstructed space for the insertion or removal of the rope. By this construction We are enabled to provide a snatch-block that is strong and durable, that is free from springs or springcatches, and that can be manipulated by a single hand with ease and facility.

Having thus described our invention, What We claim is 1. The combination, in a snatch-block, of the Y cheek-piece A, having the strap C, with its cross-bar I and the curved hook H secured thereto, and the cheek-piece B, provided with the strap D, having a closed eye or loop formed at its upper end, all constructed and arranged to operate substantially as shown and described.

This strap D isy IOO 2. The combination, in a snatch-block, of the pin and withdrawing` he hook-from the the stationary cross-bar I, having the Curved eye, as set forth. hook H journaied thereon, and the eye or loop for said hook to engage in, substantially as 5 shown and described.

3. In combination with the pvoted hook Vtnesses: H, arranged no operate as described, the chain GARRIT G. LANSING, b, Secured to the rear of said hook for holding M. R. COOK.
